The invention relates to a cooking utensil and more particularly to theclass of fireless cookers.

One of the objects of the invention-is the provision of a device of thischaracter in which the receptacle is provided with a detachable heatretaining bottom so that the receptacle may be utilized in the ordinarymanner for cooking victuals upon a stove when the bottom has beendetached and thereafter the said receptacle may be utilized as a heatretainer to preserve the contents at substantially the temperature whenthe invention consists in the construction,

combination and arrangement 'of'parts as will be hereinafter more fullydescribed, illustrated in the accompanying drawings, disclosing thepreferred forms of embodiment of the invention and pointed out in theclaims hereunto appended. In the drawin sz- Figure 1 is a verticallongitiidinal sectional view thereof. Fig. 2 is a transverse sectionalview on the line 2--2 of Fig. 1.

Similar reference characters indicate corresponding parts throughout theseveral views in the'drawings.

Referring to the drawings by numerals 5 designates generally a vesselthe body of which comprises a bottom, and an inner and outer verticalwall formed from sheet iron 6 and against theouter face of the in norvertical wall of the vessel is disposed a sheet of asbestos 7.Surrounding this sheet of asbestos 7 is an outer layer of sheet iron 8while on the outer face of the latter and the innerface of the innerside wall and the inner over the. upper edge of the side wall of thevessel. The upper mouth edge of the inner wall of the vessel 5 iscorrugated to form screw threads 10 and the outer layer of sheet iron 8is turned inwardly over the upper edge of the asbestos 7 whichterminates immediately below thecorrugated upper end portion of theinner wall of the vessel so that the extended portion of sheet iron 8will cover the outer surface and upper edge of said asbestos 7surroundingv the said inner wall of the vessel. A cover is removablyfitted on the upper end of the vessel, consisting of an inner and outerwall 11 of sheet iron and an intermediate layer of asbestos 14. Thecover 11 is formed with an,

annular flange 12 which is provided With screw threads 18 for engagementwith the screw threads 10 of the vessel. The inner and outer surfaces ofthe cover are coated with granite 15. The outer wall 11 has a handle 16secured thereto.

Extending outwardly, from the outer face of the vessel at diametricallyopposite points thereof spaced from its bottom are eyes 18 the sameadapted to be detachably engaged 'by pivotal hook members 19 suitablymounted at diametrically opposite points of a detachable soapstonebottom 20 of disk shape, the said detachable bottom being adapted to beattached to the vessel after the same has been removed from a stove ontli'e contents being heated to a predetermined tempera ture. The lowerends of the side walls of thevessel are flush with the rigid bottom, sothat when the'soapstone bottom 20 is removed from the lower ends of theside walls the said side walls will engage wtih the heat-' ing stove andthe side walls and the heat retaining material between the same will beheated.

Resting upon the inturned upper edge of the sheet iron 8 is a rubbergasket 21 so that when the lid is screwed on the vessel there will beanair tight juncture between the same.
